When should a repeated support answer become a public FAQ?

A practical question about turning repeated support replies into public FAQ records without exposing customer-specific cases.

A repeated support answer feels like FAQ material, but many replies include order context, exceptions, or personal details. I am leaning toward this rule: publish the stable policy, keep the individual decision private, and only promote the cleaned general lesson after removing case details. Where should the line be for local stores or small service teams?
